Specification of Letters Patent.

Patented Mar. 8, 1910.

Application 'inea :time is. i908. semi No. 438.790.

To all whom it may concern.'

lle it known that l', JOHN H. S'inrimxs, citizen of the United States, residing at Vernon. in the county ol. YVilbai-ge1 and State ot Texas, have invented certain new andy useful iniprovenients in Hose-Couplings, otf which the following is a specificatioii.

ling members are tlared, as indicated at 8.

ln couplings for joinedv sections ot' hose it is desirable to 'secure tight and reliable joints E to prevent leaking mg out ot the hose 'from the fittings which and to guard against` pulil lire( uentlv ha i )ons in con le'rs tor tire hose which arcretpiii'ed to withstand great pressure and linear strain.

vThe present invention supplies a coupling fulfilling the above noted conditionsI and which is simple, durable. cheap and easv ot.I manipulation. the coupling members vbeing vvided upon their inner walls with a series ot i annular grooves or ribs to make positive engagenient with the liosoto prevent possible g slipping thereo't. The coupling member 3 is .exterioi'lv threaded at its outer end to match Aheld in tixed position when tightened by.;

means ot a metallic packing clamped between them.

For a full understanding ot the invention and the merits thereof and also to acquire a knowledge ot the details of construction and the means for ellecting the result, relierenre is to be had to the following description and aecompairving drawings.

While the invention may be adapted to ditt'erent terms and coi'iditions by changes in the structure and minor details without departing trou: the .spirit or essential t'catui-es tlieieoi.still the preit'erijed embodiment is shown in the which I lligure l is a central longitudinal section ot a coupling en'iliodyiiig the invention. Fig. 2 is a transverse section on the line 2 2 ot the metallic packing ring.

torresjainding and like parts are referred io in the following description and indi.-

t ea ted in all the views of the drawings by the The numerals l and represent the ends ot' two hose sectionfs whicli'are joined by means ot' the in'ipiof'ed romprisng eomplemental coupling members il and l, a swivel rings (i and a metallic expandino' rings (i are iu the ends oi? the respective hose sections l :md 2, end portions of the hose sections'and @online the saine to the expandingrings. The outer ends ot' the expanding rings, hose sections aeeompaliving drawings, in

'liie coupling members encircle thethe internal screw threads oi the swivel connector 5. The outer end olf the coupling member l. has an outer Iiange 9 to engage with an inner iiange 10 at the inner end ot' the swivel connector. A split ring 1l is sprung into an annular groove 1;)- formed in the inner wall ot the swivel connector a short distance from the inner flange 10.

The metallic packing ring '.f' is of a size to lit between the opposing ends of the hose sectioi'is and coupling members. To prevent misplaceinent of the packing ring` aiidto have. the same at hand for immediate use when required, the same is constructed to be carried b v the swivel connector F or `this purpose the metallic packing ring is formed with an outer Harige i3 whose outer edge is tapered to match the inner sei-cw threads ot" the swivel connector. The inner screw I tlireadsrot' the .swivel connector terminate a ot lfig. l. looking in the direction of the f Fig. 3 a detail vperspective view short distance' from the ring 1Q, leaving a plain surface or space iii which the metallic l. packing. ring has free play.. Annular grooves are. termed in oppositefaces of th'e metallic packing ring and receive gaskets 14. ol' rubber. leather or like packing material eoi'iinionly employed for securing tight Ijointsin couplings. The packing gaskets 14 coupling, the letter i connection 5, expanding l packing ring 7. The tapered and inserted project a short distance beyond the faces of the metallic packing ringso as to engage with the ends of the hose sections and coupling members to insure the formation .of water tight joints. When tivo hose sections are connected by a coupling embodying the invention, the; metallic packing ring is clamped between" the sections, as indicated in Fig-p1, theljnetal portions coming togather prevent any relative play ling members which happens when a pac of the coult-4 j in of rubber, or leather, or the like, solely is interposed between the parts to be coupled, said parts having relative play when subjected to lateral strain with the result that a leaky joint is formed. By having the metallic packing ring interposed between the parts of the coupling, all are held rigidlyin alinement and there is no play resultingfrom' lateral strain, hence the engaging surfaces remain in contact. i

Having thus described the invention, what is claimed as new is:

l. In a device of the character described,t

the combination of-a coupling member, a swivel connector coperating therewith and having its interior screw threaded to within a short distance of its inner end leaving a plain portion between the extremity oit the coupling member and the inner'end of the screw threaded portion, and a metal packing arranged within the swivel connector and having an outer flange formed at its outer edge with a screw thread to match the screw threads of the Swivel connector, said outer flange being conlined in the plain space formed between the screw threaded portion of the swivel connector and the extremity of the coupling` member. u

2. In a device of the character speciiied the combination oi a coupling member having an outer flange, a swivel connector havin an inner flange to engage the outer flange of the coupling member and rovided with lan inner annular groove, ant having its interior screw threaded to within a short distance of said annular groove to leave a plain portion, forming a space, a ring sprung into said annular grooveto confine the outer flange to the swivel connector, and a metal packing arranged within the swivel connector and having an buter flange terminating at its outer edgein a screw thread which matches the screw thread portion oi Y the swivel connector, said outer flange being confined between the screw thread portion of the swivel connector and said ring.

' 3. In combination hose-pipe' ends, inner and outer metal coupling members receiving terminal portions of' said hose-pipe ends, a swivel connector for uniting the outer coupling members,pand a metallic packing arranged between the coupling members and the hose-pipe ends and having its opposite f sides grooved leaving portions intactto engage with the inner and outer metallic'coupf l l l ling members, andhaving yieldable packing inserted in the said grooves to make contact with the adjacent extremities of said hosepipe ends.

'4. 1n a device of the character described, a coupling member, a swivel connector operating therewith, and having an interior screw thread terminating short of the inner ends of the connector leaving a plain crtion between the extremity of the coup ing member and the inner end of the screw threaded portion, and a metal packing formed with an exterior screw thread arranged to match the screw threads of the swivel connector and another coupling member arranged for connection with the swivel connector and adapted to hold the packing with its exterior in the plain space formed between the screw threaded portion of the swivel connector and the extremity of the first named coupling member.

5. In a device of the character described, vthe combination of anA outer coupling member having an outer flange, a swivel connector having an inner flange to engage the flange oi' tie coupling member and provided with an inner annular groove, a ring adapted to be sprung into the annular groove and within the outer flange of said swivel connector, another outer coupling member arranged to engage the swivel connector, an inner coupling member coacting with the outer coupling member, and a packing interposed bctween the ends of the coupling members.

(i. ln combination, hose pipe ends, inner and outer metal coupling members receiving the terminal portions of said hose pipe ends, a swivel connector for uniting the outer coupling members and a metallic packing arranged between the coupling members and the hose-pipe ends and having its opposite sides grooved in registry with said hose-pipe ends leaving portions intact to engage with the opposing ends oit both the inner and outer metallic coupling members and yieldable packing inserted in said groove to enengage with the adjacent extremities of said hose pipe ends. v

In testimony whereof 'I aflix my signature in presence of two witnesses.
